SPECIFICATION formingpart of Letters Patent No. 715,480, dated December9, 1902. Application filed October 7,1902. Serial No. 126,262. lilomodel.)

T0 at whom it may concern.-

Be it known that I, JOSEPH GEORGE HUD- sPITH, a citizen of the UnitedStates, residing at Berkeley, in the county of Alameda and State ofCalifornia, have invented new and useful Improvements in Motors, ofwhich the following is a specification.

My invention relates to improvements in motors such as are designed moreespecially to be actuated by wind; and it consists in a certain peculiarmotion the novelty, utility, and practical advantages of which will befully understood from the following description and claims when taken inconnection with the accompanying drawings, in which Figure 1 is a planView of a motor constitilting the preferred embodiment of my invention;Fig. '2, a vertical diametrical section of the same, taken in the planeindicated by the broken line 2 2 of Fig. 1; Fig. 3, an enlarged detailsection taken in the plane indicated by the broken line 3 8 of Fig. 2;Fig. 4, a detail horizontal section taken in the plane indicated by thebroken line 4 4 of Fig. 2, and Fig. 5 an enlarged vertical section takenin the plane indicated by the broken line 5 5 of Fig. 2.

Similar letters of reference designate corresponding parts in all of theseveral views of the drawings, referring to which Aisa support or tower;B, a shaftj ournaled in the support and designed to be connected with apump or other device to be driven; B, a sleeve loosely mounted on theshaft B and having a sprocket-gear Ct; G, a vane connected to the sleeveB in the manner illustrated or in any other preferred manner; 1), aspider or main wheel fixed on the shaft B above the vane and havingeight (more or less) arms b and also having a bridge-bar c interposedbetween and connected to two of the arms adjacent to the outer endsthereof; E, a short shaft journaled in the bridge-bar and havingsprocket-gears d e, exactly twice the size of the gear a, fixed on itsupper and lower ends by set-screws, as shown, or other suitable means; FF, rods fixed to and rising from the arms 17 of the main wheel at oradjacent to the outer ends thereof; G G, hollow shafts loosely mountedon the said rods and equipped with blades H; I I, sprockets fixed on thehollow shafts G, preferably through the medium of set-screws, as shown;J, an endless sprocket-chain connecting the sprocket-gear c1. of thevane G and the sprocket-gear e on shaft E, and K an endlesssprocket-chain surrounding and engaging the several sprocketgears I andthe sprocket-gear d on the shaft E.

In setting up or adjusting the parts of the improved motor for operationthe set-screws fastening the several gears I to the hollow shafts G areloosened to render the gears loose on the shafts, the vane G is heldagainst movement, the main wheel D is rotated, and each blade as itreaches the position marked No. 1 in Fig. l is turned until it rests atright angles or approximate right angles to the vane C, after which thesprocket-gear on its shaft G is fixed to said shaft by tightening theset-screw in the gear against the shaft.

When all of the blades are adjusted as described above, the mill isready for operation, and it will be observed that when the main wheel isturned each blade will make one-half of a revolution incident to eachrevolution of the main wheel, and in making the half of a revolutioneach blade will be presented in various positions to the wind, asplainly shown in Fig. 1. In other Words, when each blade is in theposition diametrically opposite to position No. 1 its edge is presentedto the breeze or current of air, and in consequence it does not retardthe rotation of the Wheel. As soon, however, as it leaves the positionopposite position No. l and moves toward the latter position it beginsto gradually turn and present its outer side to the breeze until when itreaches position No. 1 its full area is presented to the breeze or wind.

The blades H are rotated as described incident to the rotation of themain wheel through the medium of the vane 0, gear a, chain J, gear 6,shaft E, gear (Z, chain K, and gears I. The chain J, shaft E, gears dand e, and the chain K are held against movement by the retention of thevane in the position shown in Fig. l, and the gears I, moving with themain wheel and engaging the chain K, turn the blades. When the windveers and the position of the vane O is changed thereby, motion istransmitted to the several blades through the connection described, withthe result that the described relative arrangement of the blades isretained.

In order to render the mill idle, it is simply necessary for anattendant to turn the vane C until the same rests in a horizontalposition, with its edge to the wind. When the vane is thus turned, thewind will turn the main wheel until the blade shown in Fig. 1 asdiametrically opposite the position No. 1 is square to the wind. Thewind will then strike the said blade at right angles and will pass ateither side of the same, with the result that the wheel will remainidle.

The blades H on the several shafts G are by preference relativelyarranged, as shown in Fig. 2, this in order to permit the blades on eachshaft to pass the blades on the adjacent shafts without striking thesame and to allow a portion of the wind to pass between the blades atthat side of the wheel which it first strikes and strike the blades atthe .opposite side of the wheel with undiminished power.

While my improved motor is designed more especially to be actuated bywind, it may also be used to advantage as a water-motor. When it is putto the latter use, the wheel is disposed vertically instead ofhorizontally,when the vane will gravitate to the position necessary toretain the blades in the proper relative positions, and the blades willbe struck by water falling from above when they are in their upperpositions and also when they are in their lower positions.

I have entered into a detailed description of the construction andrelative arrangement of the parts embracedin the present and preferredembodiment of my invention in order to impart a full, clear, and exactunderstanding of the same. I do not desire, however, to be understood asconfining myself to such specific construction and arrangement of parts,as such changes or modifications may be made in practice as fairly fallwithin the scope of my invention as claimed.

WhileIhaveshown and described the windwheel as arranged horizontally, Ido not desire to be understood as confining myself to the same, as thewheel may be arranged ver= tically or at any angle from the verticaldesired without involving a departure from the scope of my invention.

Having described my invention, what I claim, and desire to secure byLetters Patent, 1s

1. In a motor, the combination of a suitable support, a shaft journaledtherein, a wheel fixed on the shaft, rotary shafts mounted on. thewheel, and carrying blades; the blades of each shaft being arranged tolap and pass the blades of adjacent shafts without striking said blades,and means for rotating the shafts on the wheel incident to the rotationof the wheel.

2. In a motor, the combination ofa suitable support, a shaft journaledtherein, a wheel fixed on the shaft, rotary shafts mounted on the wheel,and carrying blades; the blades of each shaft being arranged to lap andpass the blades of adjacent shafts without striking said blades, a vane,and means controlled by the vane, for rotating the shafts on the Wheelincident to the rotation of the wheel.

3. In a motor, the combination of a suitable support, a shaft journaledtherein, a wheel fixed on the shaft, rotary shafts mounted on the wheeland provided with blades, and sprocket-gears; the blades of each shaftbeing arranged to lap and pass the blades of adjacent shafts withoutstriking said blades, an endless sprocket-chain surrounding and engagingthe said sprocket-gears, a vane loosely mounted on the first-mentionedshaft, and having a sprocket-gear, a shaft journaled in the wheel, andhaving sprocket-gears, one of which is engaged with the endlesssprocketchain, and an endless sprocket-chain connecting the other gearof said shaft and the gear of the vane.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.

JOSEPH GEORGE HUDSPITH.
